You can do just as much if not more damage probing as you can when popping. Don't push the probe too hard and use the correct size or you can blow out your girls. Punctures happen all the time and are not good.
Adults are harder to pop but I trust my eyes a hell of a lot more and there is nothing more accurate than what you actually see when done correctly.
OP, you said there is no one around you. Whats your location, you might be surprised?
